Gwibber-service is often trotted out as an example of a long-running process that is highly inefficient and sucks up a lot of RAM while it is operating.
The new friends-service that replaces it is much more efficient, however it would still benefit from the concept of being event-driven, only being launched periodically when it is needed rather than running all of the time. That way it can start up, use up all the RAM is wants, then exit and free all the RAM.
We've taken steps to ensure that friends-service will work well in that kind of environment, and all we're missing is some kind of cron-like userspace daemon that can invoke us periodically to download new messages.
We already have the ability to, eg, launch ourselves when somebody clicks the 'refresh' button in the gwibber client (this is done via dbus activation), however we still need to be a long-running process in order to do our periodic refreshes as well, which is wasteful of memory.
